DOR-SILL.

SPECIFICATION forming part of Letters Patent No. 351,260l dated October 19, 1886.

Application ilcdJuly 3,1886. Serial No. 207,127. (No model.)

To @ZZ whomV it may concern.-

Be it known that I, EZRA HEALEY FosTEn, of Fairmont, in the county of Martin and State of Minnesota, have invented a new and useful Improvement in Door-Sills, of which the following is a specification.

My invention is an improvement in doorsills, and has for an object to provide a sill simple in construction, which can be easily applied, and which will be efficient in use.

The invention consists in the novel construction ofthe sill, as will be hereinafter described and claimed.

In the drawings, Figure l is a perspective view. Fig. 2 is a cross-sectional View of my sill and a portion of a door adjusted for use in connection therewith. Fig. 3 is a top plan view of the sill broken away centrally, and Fig. et is a bottom plan view ofthe sill.

In carrying out my invention I prefer to -form the sill of metal, usually cast or malleable iron, as shown. The under surface ofthe sill is cored out or chambered at l l 1, said chambers being divided by ribs 2, in order to reduce the weight of the sill without lessening its strength. On its upper face the sill A is formed with a portion, B, inclining upward from its inner edge, a portion, C, joining at its upper edge the upper edge of the portion B and inclining downward toward the outer edge of the sill, and the portion D, inclining downward from the lower edge of the portion C to the outer edge of the sill. The

portion B is projected laterally at its opposite ends, forming extensions b of the sill to facilitate the placing ofthe sill into proper position.

It will be noticed that a square shoulder, 3,

is formed at the j uncture of portions C D, which 'serves to stop the intlow of water, whilewater is prevented from flowing oft the side of section D by guard-ribs d, formed at the ends of and projected upward from the portion. These ribs,it will be seen,prevent water from coming into contact with the join'tsbetwecn the doorcasing and the ends of the sill, as will readily appear. Screw-,holes4 may be formed through the sill to facilitate securing the same in place.

It is usual, in connection with my improved sill, to have the door E provided with a weather-strip, F, which, when the door is shut, rests upon the portion C, about as shown in Fig. 1. It will be seen that rain, snow, hail, and the like will be prevented from gaining access to the room, being stopped by the shoulder 3, and if it should be driven past said shoulder it will be turned back by the weather-strip F.

Manifestly the improvement can be readily applied to houses already built as well as to new ones, and it will be found durable and efficient and to present a neat appearance.

Having thus described my invention, what I claim as new is- 'Ihe improved door-sill herein described, having chambers l in its under face, divided by cross-ribs 2, provided with extensions b beyond its ends, and having its upper face formed with portions B, C, and D, a shoulder, 3, being formed at the juncture of portions C D, and the portion D being provided with end guard-ribs, d, substantially as set forth.
